Installing engineered hardwood flooring on concrete is a relatively straightforward DIY project that can add significant value and style to your home. Engineered hardwood offers a more stable alternative to solid hardwood for concrete subfloors, providing long-lasting beauty and comfort.
This guide will walk you through the necessary steps, from preparation to the finished floor.
Key Takeaways:
- Moisture test, clean, level, and install a moisture barrier if necessary.
- Acclimate your engineered hardwood before installation (48-72 hours).
- Don’t rush, and double-check your measurements and layout.

Materials and Tools You'll Need
Before you begin this exciting project, it's essential to gather the right tools and materials. This will ensure a smooth installation process and a successful outcome. Here's what you'll need:
Tools
- Moisture meter: To test the concrete's moisture level.
- Level: To check if your concrete subfloor is even.
- Trowel: For spreading adhesive (follow the adhesive manufacturer's recommendation for the correct size.)
- Tapping block and mallet: For joining the planks tightly.
- Pull bar: To help with fitting the final planks.
- Utility knife: For cutting underlayment and planks.
- Jigsaw or circular saw: For cutting planks around obstacles.
- Spacers: To maintain expansion gaps around the room's perimeter.
- Tape measure, pencil, chalk line: For marking and layout.
Materials
- Engineered hardwood flooring: Calculate the square footage of your room and add 10-15% for waste and cuts.
- Underlayment: Provides cushioning, noise reduction, and sometimes a moisture barrier. Follow your flooring manufacturer's recommendations.
- Moisture barrier (if needed): A plastic sheet to prevent moisture from the concrete from damaging your flooring.
- Flooring adhesive: Specifically formulated for engineered hardwood and your type of subfloor.
- Painter's tape: To temporarily secure planks.
- Transition strips: For doorways and transitions to other flooring types.
Recommendations
Look for high-quality materials and the correct tools for the job. Reputable flooring stores can help you choose the right products and offer advice.
Always consult your specific engineered hardwood flooring and adhesive manufacturer's instructions for specific tool and material requirements.
Preparing Your Concrete Subfloor
A successful engineered hardwood installation depends on a properly prepared concrete subfloor. This step might be the most crucial, so don't rush it! Here's how to get your subfloor ready:
Testing Moisture Levels
- Why it matters: Excess moisture in the concrete can warp, damage, and cause mold issues under your beautiful new flooring.
- How to test: There are several methods, including the plastic sheet test (simple DIY) or a calcium chloride test (more accurate). Follow the manufacturer's instructions for your chosen method.
- Acceptable levels: Your flooring and adhesive will have specific moisture limits. If the concrete is too damp, you may need to apply a moisture-mitigating sealer or wait for it to dry fully.
Cleaning and Leveling
- Remove debris: Sweep thoroughly and vacuum all dust and loose particles.
- Fill imperfections: Use a concrete patching compound to fill cracks, holes, or uneven areas.
- Check for level: Use a long level across your subfloor. Industry standards generally require no more than 3/16" deviation over a 10-foot span. If your floor isn't level, you may need to use a self-leveling compound.
Moisture Barriers
- When needed: If your moisture testing indicates higher levels, or your subfloor is prone to dampness, a moisture barrier is essential.
- Installation: Typically, this is a plastic sheeting laid over the concrete, overlapped at the seams, and taped down. Follow the manufacturer's recommendations for your chosen product.
Ignoring moisture issues or subfloor imperfections can lead to warping, buckling, or premature failure of your engineered hardwood floor. Take the time to prepare your concrete subfloor properly for long-lasting results.
Installing the Engineered Hardwood Flooring
With your subfloor prepared, it's time for the exciting part – laying down your beautiful floor! Follow these steps for a successful installation:
Acclimation
- The 'why': Engineered hardwood needs time to adjust to the humidity and temperature of your home. This minimizes shrinking or expanding after installation.
- How long: Refer to your flooring manufacturer's directions, but generally, acclimate the flooring for at least 48-72 hours in the room where it will be installed.
Planning Your Layout
- Starting point: The longest, straightest wall is usually the best place to begin.
- Pattern: Decide if you want a straight pattern, a staggered layout, or a more creative design like herringbone.
- Transitions: Plan how your flooring will meet doorways and other flooring types.
Applying Adhesive
- Follow instructions: Your adhesive will have specific directions for application and drying times.
- Trowel size: Use the trowel size recommended by the adhesive manufacturer.
- Work in sections: Spread adhesive for a manageable area of flooring at a time, to prevent it from drying out before you lay planks.
Laying the Planks
- Starting row: Lay the first row of planks along your starting wall using spacers to maintain an expansion gap (check your flooring's requirements).
- Tapping block: Use a tapping block and mallet to gently tap the planks tightly together along the joints.
- Stagger the boards: For subsequent rows, stagger the end joints to avoid creating a weak spot on the floor.
- Check as you go: Periodically check that your rows are straight and level.
Cutting and Fitting
- Around obstacles: You'll likely need to cut planks to fit around doorways, corners, or built-in features. A jigsaw or circular saw is ideal for this.
- Measure twice, cut once: This old saying is golden! Take careful measurements and create templates out of cardboard when needed to ensure accurate cuts.
Always refer to your specific flooring instructions, as some engineered hardwoods have click-and-lock systems that may have slightly different installation methods.
Finishing Touches
Once your flooring is installed, a few final steps will complete your beautiful new space and ensure your floor lasts for years to come.
Drying and Curing Time
- Adhesive directions: Carefully follow your flooring adhesive's instructions for drying and curing times.
- Before traffic: Typically, you'll need to wait at least 24-48 hours before walking on the floor and longer before moving in furniture.
Trims and Transitions
- Matching styles: Choose transition moldings that coordinate with your flooring and any adjacent flooring types (carpet, tile, etc.)
- Installation methods: Trims and transitions are secured to the subfloor with either nails, adhesive, or provided fastening systems.
- Purpose: Transitions give a clean finished look and protect the edges of your flooring where it meets different heights or other materials.
Maintenance Tips
- Sweep or vacuum regularly: This removes dirt and grit that can scratch the surface.
- Clean spills promptly: Use a damp cloth or a cleaner specifically designed for hardwood floors.
- Protective pads: Place felt pads under furniture legs to prevent scratches.
- Regularly check for signs of moisture damage: Address any issues immediately to prevent warping or mold.
Common Mistakes to Avoid
By being aware of these common pitfalls, you can ensure your engineered hardwood flooring installation goes smoothly and delivers a beautiful, long-lasting result:
- Skipping moisture testing: Excess moisture from your concrete subfloor is one of the leading causes of hardwood flooring failure. Don't rush this step, even if the concrete looks dry.
- Improper underlayment: Using the wrong type of underlayment or neglecting it altogether can lead to squeaking floors, unevenness, and moisture problems. Follow your flooring manufacturer's recommendations.
- Not leaving expansion gaps: Wood naturally expands and contracts with temperature and humidity changes. Leaving a small gap (as specified by your flooring) around the room's perimeter is crucial to prevent buckling.
- Rushing the installation: Take your time with each step. Measure carefully, ensure tight connections between planks, and allow proper drying times according to product instructions. A rushed job increases the chance of errors.
- Ignoring uneven subfloors: A level surface is essential for a stable, long-lasting installation. Any imperfections in your concrete subfloor must be addressed before laying your flooring.
By avoiding these mistakes and following the outlined steps, you'll be well on your way to enjoying beautiful and durable engineered hardwood floors on your concrete subfloor!
